Description

Technical Field

[0001] This utility model relates to the field of packaging machinery, specifically to a rotary table for transferring materials. Background Technology

[0002] Rotary pick-and-place devices are crucial equipment in the material handling field, widely used in automated production lines, warehousing and logistics systems, and packaging operations. These devices utilize rotational motion to grasp, transfer, and release materials, playing a key role in scenarios requiring continuous and efficient material handling. Existing rotary pick-and-place devices typically employ a circular or annular turntable structure, equipped with multiple stations or gripping mechanisms to achieve cyclical material transfer. However, existing rotary pick-and-place devices suffer from complex structures, difficult disassembly and replacement of key components, and require specialized tools and skills for daily maintenance and troubleshooting, increasing downtime and maintenance costs. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model innovatively provides a rotary table pick-and-place device with a more reasonable structure and easier maintenance.

[0004] This rotary table pick-and-place device includes a base, a column, a rotating disk, a rotating shaft, a rotational power source, and several vacuum nozzles. The vacuum nozzles are evenly distributed around the circumference of the rotating disk. The rotating disk is mounted on the rotating shaft, which is rotatably mounted inside the column. The column is mounted on the base. The rotational power source is mounted on the base and is connected to the rotating shaft. The device is characterized in that: the vacuum nozzles are connected to nozzle seats, which are connected to a lifting seat. An outer guide shaft is connected to the lifting seat and is slidably mounted on the rotating disk. An inner guide shaft is connected to the rotating disk and is slidably mounted on the lifting seat. The axes of the rotating shaft, inner guide shaft, and outer guide shaft are aligned on the same straight line. An annular guide seat is mounted on the column. The outer surface of the annular guide seat has a lifting guide groove along its circumference. The lifting guide groove has a horizontal section and a floating section. A guide wheel is connected to the inner side of the lifting seat and is located within the lifting guide groove.

[0005] The rotating disk is provided with a first axial bearing, and the outer guide shaft is axially slidably mounted on the first axial bearing.

[0006] The lifting seat is provided with a second axial bearing, and the inner guide shaft is axially slidably mounted on the second axial bearing.

[0007] A driven gear is connected to the rotating shaft, and the rotating power source is connected to the driving gear. The driving gear meshes with the driven gear.

[0008] The rotary table-type pick-and-place device provided by this utility model has a simple structure, low manufacturing cost, convenient disassembly and assembly, and is easy to maintain. Attached Figure Description

[0010] like Figure 1 As shown, this rotary table pick-and-place device includes a base 1, a column 2, a rotary table 3, a rotating shaft 4, a rotary power source 10, and several vacuum nozzles 5 (the vacuum nozzles 5 are connected to a nozzle negative pressure controller 13). The vacuum nozzles 5 are evenly distributed around the circumference of the rotary table 3. The rotary table 3 is mounted on the rotating shaft 4, which is rotatably mounted inside the column 2. The column 2 is mounted on the base 1. The rotary power source 10 is mounted on the base and is connected to the rotating shaft 4 for transmission. During operation, the rotary power source 10 drives the rotating shaft 4 to rotate, which in turn drives the rotary table 3 to rotate. This causes the vacuum nozzles 5 on the rotary table 3 to move accordingly, picking up the material and transferring it from point A to point B before putting it down.

[0011] like Figure 3As shown, the vacuum nozzle 5 is connected to the nozzle seat 50 (replacing or repairing the vacuum nozzle 5 is very convenient; simply remove the vacuum nozzle 5). The nozzle seat 50 is connected to the lifting seat 9. An outer guide shaft 7 is connected to the lifting seat 9. The outer guide shaft 7 is slidably mounted on the rotating disk 3. An inner guide shaft 8 is connected to the rotating disk 3. The inner guide shaft 8 is slidably mounted on the lifting seat 9. The axes of the rotating shaft 4, the inner guide shaft 8, and the outer guide shaft 7 are on the same straight line. Through the inner guide shaft 8 and the outer guide shaft 7 (two points determine a straight line), the vacuum nozzle 5 will not rotate during its revolution and will maintain a fixed position on the rotating disk 3. In addition, an annular guide seat 6 is installed on the column 2 (the annular guide seat 6 is fixed). The outer side of the annular guide seat 6 is provided with a lifting guide groove along the circumference. The lifting guide groove has a horizontal section 60 and a floating section 61. A guide wheel 90 is connected to the inner side of the lifting seat 9. The guide wheel 90 is located in the lifting guide groove. During operation, the rotary disk 3 moves the rotating vacuum nozzle 5 and the lifting seat 9. When the guide wheel 90 on the lifting seat 9 moves in the horizontal section 60 of the lifting guide groove, the vacuum nozzle 5 and the lifting seat 9 do not move up or down, but only rotate horizontally. When the guide wheel 90 on the lifting seat 9 moves in the floating section 61 of the lifting guide groove, the lifting seat 9 moves up and down under the guidance of the guide wheel 90 (both the inner guide shaft 8 and the outer guide shaft 7 move up and down). When the lifting seat 9 descends, the vacuum nozzle 5 begins to suck up or lower the material below. When the lifting seat 9 rises, the vacuum nozzle 5 rotates with the material, moving the material from point A to point B. This rotary disk type pick-and-place device has a simple structure, stable operation, low manufacturing cost, and is easy to maintain.

[0012] In order to make the outer guide shaft 7 move up and down more smoothly, a first axial bearing 70 is provided on the rotating disk 3. The outer guide shaft 7 is axially slidably mounted on the first axial bearing 70. The first axial bearing 70 can make the outer guide shaft 7 move up and down more smoothly without resistance.

[0013] Similarly, in order to make the inner guide shaft 8 move up and down more smoothly, the lifting seat 9 is provided with a second axial bearing 80. The inner guide shaft 8 is axially slidably mounted on the second axial bearing 80. The second axial bearing 80 can make the inner guide shaft 8 move up and down more smoothly without resistance.

[0014] like Figure 2 As shown, a driven gear 12 is connected to the rotating shaft 4, and the rotating power source 10 is connected to the driving gear 11. The driving gear 11 meshes with the driven gear 12. Driven by the rotating power source 10, the driving gear 11 drives the driven gear 12 to rotate, which in turn drives the rotating shaft 4 to rotate.
